Title: Specific Heat Capacities of Metals Experiment Date: 3/28/2012 Report Date: 4/4/2012 Purpose: The purpose of the lab is to measure the specific heat capacities of aluminum‚ steel and brass. Theory: The amount of heat (ΔQ) required to change the temperature of an object is proportional to the mass (m) of the object and the temperature change (ΔT) of the object. ΔQ= cmΔT where c is called as the specific heat capacity of the material. In the calorie units system the unit of quantity

Heat of Formation of Magnesium Oxide Objetive: To determine the heat formation of MgO (Magnesium Oxide) using Hess’s Law‚ which states the heat within a chemical reaction is independent of the pathway between the initial and final states. Introduction: Chemical reactions require heat energy to complete‚ called an endothermic reaction‚ or produce heat energy‚ and thus called an exothermic reaction. The heat energy produced by such reactions can be measured using a calorimeter‚ a piece

Importance of Water The water that we consume today is the same water since pre historical period .The importance of water has not changed; the only difference now is the purity and efficiency of it. Barbara Kingsolver‚ a famous American writer‚ explains the problems concerning water in her article‚ “Fresh Water.” Humans’ inclinations to excessively use natural assets have caused climate change and drought in many parts of the world‚ making it difficult for many people to access clean and fresh water.

The Effects of Using the Heat Shock Treatment to Deliver a Vector in Genetic Transformation Introduction: In this experiment we are testing what is required for E. coli to successfully grow on LB (Luria Broth) plates with ampicillin and determining if any genetic transformation has occurred. By combining +pGLO LB and ampicillin we should get an ampicillin resistant gene and by using –pGLO we should create a non-genetic resistant bacteria. The pGLO plasmid has the GFP (green fluorescent protein)

mechanically. The driver or one of several mechanical control systems controlled all the engine systems. For instance‚ before the introduction of sensors and microcontrollers‚ a mechanical distributor selected the specific spark plug to fire when the fuel-air mixture was compressed just so. The timing of the ignition was the control variable. The mechanically controlled combustion process was not optimal in terms of fuel efficiency. Modeling of the combustion process showed‚ for increased fuel efficiency
